they do/will, but since they have so much speed (energy), it takes millions and millions of years to slow down enough that they fall out of orbit

Because they are moving at a sufficient rate of speed that causes them to fall at the same rate they are moving around the sun, so in essence, they are falling over the horizon which means that they will never hit the sun until they slow down enough (over billions of years) that their orbits decay.

Tie a string to a small stone, and swing it around about your head. The string pulls the stone toward your head, but it does not hit you. Same principle exactly; just replace the pull of the string by the pull of gravity.

its really inertia (newton) and for every actions theres an equal n opposite reaction [suns gravity acting on the momentum objects have around it to Not orbit it] so newton again :]

Because they have enough energy to be in orbit, so the falling and flying out forces balance each other out.

it's too far, i always thought that they would melt b/c of the incredible heat. they wouldn't make it anywhere near it if they were headed in a direct path.
